Final answer:
Primary memory refers to RAM which is volatile and directly accessible by the CPU, used for data currently being processed. Secondary memory includes HDDs and SSDs which provide non-volatile storage for long-term data retention.
Step-by-step explanation:
Types of Memory in Computing
The two primary types of memory used to store programs and data in a computing context are primary memory and secondary memory.
Primary Memory
Primary memory, also known as main memory or RAM (Random Access Memory), is the computer's main storage area that is directly accessible by the CPU. It is used to store data that is actively being used or processed by the system. Since it is volatile, its contents are lost when the power is turned off.
Secondary Memory
Secondary memory refers to storage devices that are not directly accessible by the CPU and include HDDs (Hard Disk Drives), SSDs (Solid State Drives), and other forms of storage such as USB drives and CDs. Unlike primary memory, secondary memory is non-volatile, meaning it retains data even when the computer is powered down, providing long-term data storage.
